Open the pineapple cans and collect the juice. If there’s less than 1½ cups, top it up with water. Put the juice in a big pan with the corn syrup and half the sugar. Warm it gently while stirring to dissolve everything. Let it bubble lightly for 4 minutes.

Turn the heat down low, then add the pineapple rings in a single layer, keeping space between them. Keep cooking, flipping the rings often so they get evenly coated and don’t stick.

Let everything simmer for about 45 minutes. Check often to keep them from sticking, and wait until the pineapple slices lose their cloudiness and become see-through.

Take the rings out of the syrup and arrange them on a rack with parchment underneath. Let them dry all the way until they’re tack-free—overnight works well. For quicker drying, pop the rack on a baking sheet and place it in a 200°F oven for 30 minutes.

When fully dried out, dip each pineapple ring in the remaining sugar sitting in a shallow dish. Give them a good toss until fully coated. Keep them in an airtight container at room temperature to store.
